[0027] When the seedling feeding assembly needs to take seedlings from the hole tray 6, the piston rod of the first cylinder 16 is in a backward retracted state, and the piston rod of the second cylinder 17 is in a forward retracted state. At this time, the seven seedling feeding claws 3 are arranged in a row along the left and right directions and are in a seedling taking state, so that they are consistent with the arrangement shape of a single row of seedlings on the hole tray 6 to be taken.

[0028] When the seedling feeding assembly needs to feed the removed seedling lump into the transplanter, the piston rod of the first cylinder 16 is controlled to extend forward, and the piston rod of the first cylinder 16 drives the pull plate 23 to move forward, and the pull plate 23 drives the second seedling feeding claw 19 to move forward together. At the same time, the extension plates 24 on the left and right sides of the pull plate 23 move forward in the front push-pull gap 26 of the left and right front carriages 25 respectively. When the extension plates 24 contact the front limit baffle on the front side of the front carriage 25, it will push the front carriage 25 to move forward together, thereby driving the first seedling feeding claw 18 and the third seedling feeding claw 20 to move forward together, until the piston rod of the first cylinder 16 extends forward into place, at which time the second seedling feeding claw 19 is located a certain distance in front of the first seedling feeding claw 18 and the third seedling feeding claw 20.

Then the seven seedling feeding cylinders 10 for taking and feeding the seedlings 3 move, drive seven groups of seedling needles 11 to extend downward and insert into the seven seedlings in the first row of the plug tray 6, and grab the seedlings. Afterwards, the vertical motion component moves, drives the seven seedling feeding claws 3 to move up, and extracts the seven seedlings grabbed by them upward. Then the horizontal motion component moves, drives the seven seedling feeding claws 3 and the seven seedlings grabbed by them to move forward to the seedling throwing position. The piston rod of the first cylinder 16 and the piston rod of the second cylinder 17 are controlled to extend, so that the seven seedling feeding claws 3 are dispersed to form a circular shape, which is consistent with the circular shape of the seven seedling throwing cups 32 on the single disc rotary cup transplanter. Then the vertical motion component moves, driving the seven seedling feeding claws 3 to move down as a whole, and the seven seedlings caught by them are respectively placed into the seven seedling throwing cups 32 of the transplanter below, and then the piston rods of the seedling feeding cylinders 10 of the seven seedling feeding claws 3 are retracted upward, driving the seven groups of seedling needles 11 to move up, and pull them out from the seven seedlings respectively, that is, the seven seedlings are taken out of the hole tray 6 and automatically put into the seven seedling throwing cups 32 of the transplanter.

[0031] Repeat the above steps, grab the second row of seedlings on the plug tray 6 and put them into the seedling cup 32 of the transplanter, and repeat this process until all the seedlings in the plug tray 6 are taken out and put into the transplanter. The whole process is highly automated, which greatly improves work efficiency and reduces the labor intensity of operators.
